We could smell something musty in the hallway closet but never found anything. Turned out to be a slow leak behind the wall from an old pipe. They found it in under an hour and the smell was gone once the work was done.

Good to know
Mold Odor Removal in Fontana, CA: common questions
Can there be mold if I can't see any?
Yes. Mold often grows inside wall cavities, under flooring, or in ductwork long before it becomes visible on a surface. A persistent musty smell is one of the most common signs of hidden growth.
How do you find odor without visible mold?
We walk the space to locate where the smell is strongest, then use a moisture meter to check nearby walls, floors, and baseboards. If needed, we open a small access point to confirm what's happening inside a cavity.
Is a musty smell in my basement normal for California homes?
A faint concrete smell can be normal, but a strong, persistent musty odor usually isn't. It's worth having checked, especially in basements near foundations that see spring runoff.
How soon can you start mold odor removal in Fontana?
We answer our line 24/7 and can usually reach a Fontana home the same day you call, sooner for an active leak.
Will air fresheners or ozone machines fix the smell?
They can mask odor temporarily but don't address the source. If mold or trapped moisture is causing the smell, it will typically return once the treatment wears off.
What if you can't find a source?
It happens occasionally, especially with faint or intermittent smells. We'll tell you honestly if we don't find active moisture or mold rather than recommending unnecessary removal.
How do you keep the mold from coming back after mold odor removal?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Fontana home.
Do you serve Fontana?
Yes. We cover all of Fontana, including Bloomington, Rialto, Sunnyslope, and the rest of the Fontana area. We are based in Grand Terrace, about 15 minutes from our Grand Terrace base, and answer our own phone around the clock.
